AIIPPIARATUS non ozonrzme FLUIDS.-

To all whom it may concern."

Be it .known that I, SIEGFRIED HELD, a citi v zen ofthe United States, residing atChicago, in thecounty of (Jook and State of Illinois, have invented certain new and useful Improvements in Apparatusfor ()zonizing Fluids, of which the following is a specificationr My invention relates to improvements. in

apparatus ..for ozoni'zing fluids and has especial reference to convenient devices of this character for purifying water.

One of the objects-of my invention is to provide an ozonizing structure designed for purifying water and especially adaptable for domestic or home use.

In my water purifying apparatus I emwater completely'destroys it and removes all putrescible and other offensive organic matter and odoriferous gases, thus rendering the water hygienic, wholesome and fit for human consumption.

'l o enhance the qualities and to improve the color'of the water it is advantageous to treat it at the rate atwhich it is being consumed and to avoid the necessity of providing a powerdriven means for-introducing the ozonized air intothe body of flowing water ;I utilize an inspirating effect of themoving column of water to draw the air through the ozone generator and into the mixing chamber.

In carrying these features of my invention into effect I close an electric circuit to energize the ozone generator by an instrumentality, usually a manually operable means,'such, for example,.as a lever or handle of a bibb or faucet, which is movable to open a valve controlling the water supply.

In the particular embodiment illustrated in the accompanying drawings which form a part hereof, the device is shown to be selfcontained and all that will be requisite to its use is that whenbeing installed it'be connect- Application filed May 25,

In all the views the same reference char-- the device shown a'cters are employed to indicate'similar parts. p 20 is an air tight water receptacle having afrubber band26, closes the bottomof the waterreceptaclei A cup-shaped member 27 of the receptacle, is'secured to the mainportion thereof by a series of hooks 28 andby threaded rods 29 having eyes 30 engaging thefhooks and tahing through perforations 31, the edge of'said cup-shaped member 'being held in place by means of win ed nuts 32. v 'llhis "cup-shaped member is a so provided with an inwardly-projecting circumferential head 83 bearing against the side of the rubber band 26 and thus water tight connection is made between the cup-shaped member 27 and the interior of the water receptacle'20. Cup-shaped member 27 con- 1 tains two scrapers 34, there being one .on either side of the axial center, yieldingly pressed against the filter plate 25 by a spring 35 which surrounda central stud 36, and which passes through the lower wall 27 of the cup-shaped member. A handle 37 is the means by which the scrapers or knives may be rotated to clean the lower surface of the filter plate. In the side wall 38 of the cupshaped member is a water conducting fitting 39, controlled by a stop cock 40.

The water receptacle 20 is provided with an inset wall 41 closed to the main portion of the receptacle, as at 42 and 43, thereby providing 'a chamber 44 within which to contain the working mechanism of the apparatus. A cover plate 45 overlies'the opening in the chamber 44 and is connectedto the main portion 20 0f the water receptacle, as at 42 and 43. Ttis preferably locked in position, by means of the lock 46, so that it may not be removed, the interior mechanism thereby becoming non-accessible to unauthorized persons.

A water discharge spout 48 is secured to the front wall, or to the cover 45 of the compartment, 44, and communicates by a fitting 49,.with the casing 50, which contains the water and ozone mixing chamber 51. The

stop cock fitting 52 is connected to the bottom wall 41, surrounding the chamber 44, and is provided with a shut-off valve 53, the stem 54 of which is accessible through an opening 56 provided for the purpose in the 7 cover 45. -The upper portion of the fitting 52 is annularly enlarged, as at 57, for a con nection of a fitting 58, therewith, by a screw 59. A water conduit passes through the parts 57 and 58 into a pipe 61. The screw 59 is also accessible through an opening 63 providedin the cover 45 for that purpose. A gasket 64 is placed between the fitting parts 57 and 58 to make a water tight joint. The pipe 61 is secured to a fitting 67 that enters a chamber 68 in which the water and ozone are mixed, and which is surrounded by a fitting 69 that is connected to another fitting 70, by a' union 71. A valve 72 is located inside of the-chamber 68 and controls a port 73 through which the water is admitted into a nozzle 75. The valve stem 76 passes through the upper end of the casing 69 and through a suitable packing 77 The upper end of the shaft or. spindle 76 isprovided wlth a head 78 having collars 79 ,.and'80 and a space 81 in which is contained the forked ends 82 of alever 83, that is pivoted, as at 84, to a bracket 85, fixed to a ring 86,v that 1s secured to the upper end of the casing 69, as by screw 87. The valve 72 is normally held closed on its seat 73 by a spring '88.

The valve is opened by an electro-solenoid 89, having an axially reciprocatable core 90,

eaosae from which projects a stem 91. The stem 91 is provided on its upper end with a head 92, slotted for the end of the lever 93 and containing, preferably, a roller 94. The lever 93 is also pivoted, as at 95, and is provided with a slotted downturned end 96 and is also, preferably, provided with a roller 97 for engaging the upper surface of the lever matically close the valve 72., thus shutting ofi the water supply. The casing 98,.surrounding the chamber 70, is connected to the casing 50 containing the mixer 51, as at 99.

The ozone generator 100, shown in cross section in Fig. 10, and which constitute the subject matter of my copending application,

Serial No. 228,326, filedApril 13, 1918, is supported on a plate of insulating material 101 by standards 102, .103 and straps 104, 105. The insulating plate 101 is secured to the cover by means of standards 106, 107, 108 and 109. I

The air intake end of the ozonizing device is surrounded by an annular casing 110 and the discharging end 111 for the ozonized air is connectedby a pipe 112 to a fitting 113, in the casing-98. In the chamber 70 the water and ozonized air first meet and are directed by the inspirating effect of the moving column of water into the mixing chamber 51, through the opening 114 and the main tube 115. The water and ozonized air together pass downwardly through the tube 115, in the direction of the arrows, into the chamber 116, from which they pass througha series of smaller tubes 117 into a casing 118, and from this they pass into another series of small tubes 119, from the upper end of whichthey pass into the main chamber 51. After the water and ozonized air are thoroughly mixed, in their passage through the various tubes described, they finally pass out of the chamber 51 through the fitting 49 and the spout 48, by which the purified water is delivered.

Located at the lower end of the solenoid 89 is an air dashpot 120 containing a piston 121 connected to the solenoid core 90 by a f stem 122. The piston is perforated, as at 123, and the perforation is covered by a flap valve 124, so that when the piston is moved upwardly by the stem, 122, the valve is closed and the air'contained within the dash pot is forced out through the pipe 125 into the annular casing 110. 1

"When the electric solenoid is first energized, this efiect, by operation of the dashpot, causes an impulse of air to pass through the ozone generator 100, and into the casing 70, in which the water is to be received when the valve 72 is opened, substantially at the same time. After the water passes from the nozzle 75 into the opening 114 the inspirating effect of the water will have sufiicient force to draw subsequent streams of air through the dashpot 120, the .port 123 being The direction of the air through the ozone generator is shown in Fig. 10,,by the arrows.

A pipe 126 passes through the water chamber of the water receptacle, and the wall 41 v of the chamber 44, through which wires 127, 128 may pass to the resilient, electrical conducting tongues 129, 130, respectively. These tongues are supported by an insulating plate 131 which is fixed to the structure by a cleat 132. Terminals 133, 134 are secured'to the plate 131 and are provided with upwardly projecting contact points 135, 136, respectively. These contact points are brought into electrical connection with the relatively stationary, resilient tongues 130, 131, as clearly shown in Fig. 4, when the insert supporting the operative mechanism heretofore described, is adapted to be placed in the-chamber 44 and which is secured to the cover 45 of said insert.

An electric switch 140 is secured to the cover 45, consists of a plate 141 upon which is mounted a switch lever 142, pivoted, as at 143, and'adapted to close the contacts 144, 145 when in circuit closing position. A stem 146 is supported by brackets 148,. mounted upon the plate 141, and is projected through the wall 45 of the cover. On theOuter end is mounted a push button 149 which is held resiliently extended by a spring 150.- A switch-shifting lever 151 is pivoted at 152, and is provided with a pin 153 which enters the slot 154 in the stem 146 of the switch operating mechanism. The upper end of the lever 151 is enlarged, as at 156, and on the. laterally extending surfaces of the enlarged head 156 are projections 157 which engage the lever 142. A spring 158, in connection.

with the pin and slot of the stem 146, giyes the switch member 142 a quick snap action when the push button 149 is pressed inwardly,

as well understood by persons versed in the art, when considering devices of th1s character. The pivoted switch member 142 will snap into connection with the contacts 144, 145, by pressure on the push button, and the spring 150 will cause it to snap out of connection when the ZPush button 149 is released. The upper contact 144 of the switch is connected by a wire160 to a terminal 133 and the lower contact 145 is connected by a wire 161 with a terminal 162 and by a wire 163 to the solenoid 89 and from thence by a wire 164 with the terminal .134: This puts the switch and the solenoid in series circuit with the primary circuit broughtinto the apparatus over the wires 127, 128. A transformer 165 is connected to the terminals 133, 134 by wlres 166, 167. The secondary circuit of the transformer is connected by wires 168 to one end of the ozone generator, as at 169, and

the wire-170 to the terminal 171. The terminal 171 is also connected to the terminal 172 by a wire 173.

The primary circuit of the transformer is closed by the switch 140 over the circuit just described, when the push button 149 is pressed inwardly, thereby energizing the.

solenoid to open the water valve and energizing the ozpne generator to ozonize the air drawn into and through. the. device by the action of the moving water.

The cover 45 containing mechanism may be removed from the chamber 44 by unlocking it and by shutting'oif the water by closing the stop cook 54 through the opening 56 and by removing the screw 59, thnough the opening 63 to separate the parts 57 and 58 of the fitting 52. The latter being the only part, except the electrical contact block 131, that is not removable from.

the chamber 44.

The faucet, or. delivery spout 48, is arranged so that should a meddlesome person place his finger over the delivery orifice, that the operative v water, or other liquid, would not back up into the mixing chamber and flood the ozone generator, through the pipe 112. To prevent this, I provide one or more perforatibns'48 thespout, through which the liquid will flow, should the delivery end of the spout be closed. I

To guard these orifices, when they arelocated at the end of the spout, I provide a shroud 48 to overlie the cup-shaped terminal member 48. This prevents closing of the orifice 48 bv ordinary means and the orifices permit the liquid to flow freely should'the elivery normal orifice 48 be closed. 1 V Besides using the apparatus for purifying water, it may be beneficially employed for many other purposes in conjunction with flowing liquids, for example, obnoxious fish glue liquid may be de-odorized and made innocuous oils may be thickened by the ozonizing process, and becoming resinous, made suitable for varnish; aging of flcertain liquids and spirts may also be accomplished by the practice of my invention. While I have herein shown, a bodiment of my invention for purposes of clear disclosure, it is manifest that changes may be made in the arrangement and con-.
